The all-time high for passenger traffic, set in 2007, is 32.2 million.

Airline officials attributed the uptick to new air service added by carriers including American Airlines, Frontier Airlines, Spirit Airlines, Southwest Airlines and Delta Air Lines. Those five carriers collectively launched non-stop flights to 27 new destinations in 2018. The airport also added Irish carrier Aer Lingus last year.

International passengers increased six percent from 2017 to 4,246,171. That was the largest percentage increase since a 17.1 percent surge in 2004.

Cargo tonnage jumped 20 percent over the previous year, reaching 555,327 and eclipsing 500,000 for the first time since 2008.

“Our airport team continues to work tirelessly with our airline, tourism and business partners to attract new air service whether it’s more flights to more cities by our established carriers or bringing in a new airline,” said airport CEO Chellie Cameron. “Our 2018 numbers show how the team’s efforts produced real results. We are encouraged by the upswing in passengers, operations and cargo handling and are eager to maintain this positive trend.”
